text: In the food industry, levan is incorporated due to its prebiotic effects, cholesterol lowering ability, and adhesive properties. It also occurs naturally in low amounts in food for human consumption. Levan is also included in many dairy products as fiber or sweetener. Commercial, non-alcoholic beverages use levan as well in ultra-high-fructose-syrups. Interestingly, levan causes useful bacterial growth and proliferation which can be especially important in the gut because it causes a decrease in population of the pathogenic bacteria.
